Benefits of technology

[0025]By varying the colors of the rubber plugs to be attached to a plurality of electric wires to be connected to a waterproof connector and a non-waterproof connector, even when all the electric wires have a single color, the circuits of the electric wires can be identified by the rubber plugs. As a result, the number of colors for electric wires can be reduced, and a plurality of electric wires to be connected to a single connector can have a single color, for example. Therefore, there is an advantage in that the operation of covering a large number of electric wires with sheets in order to conceal their colors, and the like can be made unnecessary.

Problems solved by technology

Therefore, a large number of colors are used for electric wires, and some electric wires have patterns of stripes, dots, and the like that have colors that are different from that of a ground color (base color), which is a single color, thus causing a problem in that it is expensive to manufacture and manage a large number of types of electric wires.

first embodiment

[0050]FIG. 5 shows a modified example of a

[0051]In the modified example, an insulating coating barrel 30a of a crimp terminal 30 is crimped to and fixed to a small-diameter portion 5s that is obtained by making a portion to the front of the waterproofing rubber plug 5 thin. It should be noted that in the drawings, 30b denotes a core wire barrel, and 30c denotes an electrical contact portion.

[0052]The other structures and effects are the same as those of the first embodiment, and thus their description will be omitted.

second embodiment

[0053]FIGS. 6(A)-7(B) show a

[0054]In the second embodiment, a plurality of (fourteen) electric wires 1 have a single color, namely black, and these electric wires 1 are inserted into and locked to a multi-contact non-waterproof connector 40 (having terminal accommodating chambers arranged in two rows in the vertical direction and in seven columns in each row). As in the first embodiment, rubber plugs 50 that differ in ground color are fitted on the electric wires 1.

[0055]The rubber plugs 50 are not waterproofing rubber plugs, and are used as circuit identification indicators. In the same manner as the rubber plugs 5 of the first embodiment, the ground colors of the rubber plugs 50 have different colors and have no stripes, no dots, or the like.

[0056]The rubber plugs 50 differ in shape from the waterproofing rubber plugs of the first embodiment. As shown in FIG. 6(A), each rubber plug 50 has a thin-walled cylindrical tube shape that has the same cross-sectional shape along the entire...

Abstract

Colors for electric wires are reduced. A plurality of electric wires to be connected to a single connector have a single color, rubber plugs are attached to boundary portions that are each located extending from a terminal for connection to a connector connected to an end of the electric wire to the insulating coating of the electric wire, and the rubber plugs have different colors for identification.

Description

TECHNICAL FIELD[0001]The present invention relates to electric wires with identification indicators, and is preferably used particularly in cases where a large number of electric wires included in a wire harness to be laid out in a vehicle are connected to a connector.BACKGROUND ART[0002]When a plurality of electric wires are bundled together and laid out, it is necessary to identify the respective circuits of these electric wires for the purpose of a wiring operation in which the electric wires are connected to a connector and for cases of malfunctions and maintenance during use. In order to identify these circuits, for example, the insulating coatings that cover the core wires of the electric wires may be colored.[0003]In particular, wire harnesses to be laid out in automobiles are fabricated by bundling together a large number of electric wires, and as the number of circuits and the size of a connector increase, it is necessary to identify the circuits of an ever larger number of...
